MassMutual Financial Group is moving its downtown Pittsburgh office to larger space next week and adding a second location north of the city by month-end to accommodate growth.

The company added 10 employees since the start of the second quarter, bringing employment here to 80. Most will move from the current space at 11 Stanwix to 15,461 square feet at 6 PPG Place on June 13.

But seven, a mix of new hires and veteran staffers, will form the nucleus of a new Cranberry office opening later in June. MassMutual expects to grow that to 12 within a year.
